Patented Nov. 26, 1929 UNITED STATES WILLIAM J. DUVALL, OF ST. LOUIS, MISSOURI, ASSIGNOR TO SMITH 8a DAVIS MANU- FACTURING COMPANY, OF ST. LOUIS, MISSOURI, A CORPORATION OF MISSOURI BED CONSTRUCTION Application filed September 28, 1927. Serial No. 222,477.

This invention applies to beds and more particularly to fastening devices for the same.

One of the objects of this invention is to provide a fastening by means of which the 'side bars may be attached to the head and foot frames of the bed in a simple and convenient manner.

Another object is to provide such a fastening which will become wedged so as to bind the same against accidental displacement.

Another object is to provide such a fastening which will be cheap to manufacture and reliable and secure in service.

Further objects will appear fromthe following description, taken in connection w1th the accompanying drawing, in wh1ch Figure 1 is a perspective view of part of a bed, showing a fastener embodying this 1nvention, in disconnected relation; and

Figure 2 is a side view of the fastenlng with a part shown in section on line 2-2. of Figure 1 in order to show the canting action.

In the usual bed construction, particularly in the case of metal beds, the main frame of the bed consists of head and foot frames joined by a pair of side bars upon which the bed spring is supported. The side bars are made detachable from the head and foot frames so that the bed may be taken down for movement or storage.

The present invention provides a detachable fastening by which the side bars may be secured to the head and foot frames. In the accompanying drawings, 1 designates a base plate which may be secured in any convenr ent manner to the head or foot frame 10. The

base plate 1 is provided with a raised or embossed portion 2 having a gradual slope from the face of the plate 1 at its upper end to a suitable height above the plane of said face at its lower end, as shown in Figure 1. Mounted on the plate 1 is a pair of headed pins 3 and 4. The former of these is mounted near the origin of the embossed portion 2, while the latter is mounted near the highest part of said embossed portion.

The side bar 8 of the bed is equipped with an angle plate 7, one flange of which is riveted or otherwise suitably fixed to the side '1 bar 8, and the other of which is provided with keyhole slots 5 and 6 spaced so as to be able to engage the pins 3 and 4.

l/Vhen the bed is assembled, the slots 5 and 6 are passed over the heads of the pins 3 and 4 and the side bar is then lowered so that the necks of the pins 3 and 4 engage in the narrow portions of the slots 5 and 6. During the downward movement, the lower part of the outstanding flange of the plate 7 rides up the inclined surface of theembossed portion 2. This movement tends to tip or cant the plate 7 relatively tothe plate 1 and the pins 3 and 4. In such canted position, the plate 7 is wedged under the heads of the pins, 3

and 4, as clearly shown in Figure 2, in which the plate bears at the" points A, B and C. This wedging action tends to bind the fastening securely together so as to avoid any pos sibility of accidental displacement. It will be noted that the pin 4 guides the plate 7 in its movement along the boss 2 so that it will move to the highest point of said boss and securely wedge the plate under the head of the pin 3. A fastening is thus provided which, while being easily detachable, is securely wedged when in attached position.

It is obviousthat various changes may be made in the'details of construction, within the scope of theappended claims, without departing from the spirit of this'invention.

It is, therefore, to be understood that this invention is not limited to the specific details shown and described.

Having thus described the invention, what is claimed is:

1. In a bedstead corner fastening, a post plate having a vertical plane face, a wedge shaped projection on said face beginning medially of the plate and extending clownwardly and forwardly thereof, .a headed pin extending forwardly of the plate and located substantially. at the top of the projection, a second pin situatedon the projection below the first pin, a rail plate having an upper slotted opening to receive the first pin and a second opening to receive the second pin, the length of the headed pin and the thickness of the rail plate being such that when the plates are assembled, the upper and lower parts of the rail plate only are in contact with the post plate and projection, and the medial part is forced outwardly against the head of the 2. In a bedstead corner fastening, a post plate having a vertical plane face, a wedgeshaped projection on said face beginning medially of the plate and extending clownwardly and forwardly thereof, a headed pin extending forwardly of the plate and located substantially at the top of the projection, a rail plate having a slotted opening to receive said pin, the length of the pin and the thickness of the plate being such that when the plates are assembled the upper and lower parts of the rail plate only are in contact with the post plate and projection, the medial part being forced outwardlyagainst the head of the pin, and means to prevent relative rotation between said plates.

3. In a bedstead corner fastening, a post plate having a vertical plane face, and a face portion extending angularly relative to said plane face, said angular portion beginning medially of the plate and extending downwardly and forwardly thereof, a headed pin extending forwardly of the plate and located approximately at the top of said angular portion, guiding means located on said plate adjacent said pin, a rail plate having a slotted opening to receive said headed pin and means cooperating with said guide means thereby to prevent relative rotation between said plates, the length of the headed pin and the thickness of the rail plate being such that whenthe plates are assembled the upper and lower parts of the rail plate only are in contact with the post plate and angularly extending face, the medial part being forced outwardly against the head of the pin.

4:. In a bedstead corner fastening, a post plate having a vertical plane face and an angularly extending face beginning medially of the plate and extending centrally of said plane face, a bayonet pin extending forwardly ofthe plate and located substantially at the top of the angular face, a rail plate having a bayonet slot to cooperate with said pin, the length of the pin and the thickness of the rail plate being such that when the plates are assembled the upper and lower parts of the rail plate only are in contact with the I 0st plate and angular face, the medial part eing forced outwardly against said bayonet pin, and means to prevent relative rotation between said plates.

In testimony whereof I aflix my signature this 20th day of September, 1927.

WILLIAM J. DUVALL.
